A balancing weight for balancing a wheel of a vehicle has a body of non-ferromagnetic material providing a major portion of the balancing weight's mass and a ferromagnetic inlay for holding the balancing weight by magnetic force. The ferromagnetic inlay provides a minor portion of the balancing weight's mass. A weight applicator has a magnet for interacting with the ferromagnetic inlay of the balancing weight and holding the balancing weight.

A fixture for sticking balance blocks to the surface of a hub includes a base, in which a fixed plate is welded to one side of the upper end of the base, a slide rail butted to the fixed plate is connected to the other side of the base by bolts, a sliding block is connected to the slide rail in a sliding manner, the middle positions of the fixed plate and the sliding block are respectively connected with a first roller and a second roller of the same type by bearings, each of the first roller and the second roller is sleeved with a rubber sleeve of the same specification, and a support table is mounted under the base.

A ballasting weight (20) having a length, width, thickness, first side, second side, top, and bottom, and a cross-sectional profile comprising a notch forming a groove (28) extending longitudinally along the length of the first side of the ballasting weight (20), wherein the groove (28) is operatively adapted so as to facilitate the automatic dispensing and/or applying of the ballasting weight (20), e.g., on the rim flange of a wheel rim adjacent to its flange lip, and a device for so dispensing and/or applying the ballasting weight.

A fan of the invention includes an impeller having a plurality of blades and rotating around a rotation axis, and at least one balance weight having at least one claw portion and attached to the impeller to correct the center of gravity of the impeller. The impeller has a circumferential convex portion formed along the circumferential direction, and on which the claw portion is hooked to restrict a range of movement of the balance weight in the radial direction of the impeller, and at least one radial concave-convex portion formed along the radial direction, and on which the claw portion is hooked to restrict the range of movement of the balance weight in the circumferential direction of the impeller.

A balanced turbomachine part including one angular sector arranged to form a balancing ring centered about a ring axis. The angular sector includes a plurality of fasteners, a bearing face having a complementary shape to the balancing ring, the angular sector bearing on the bearing face. The part further includes a plurality of balancing masses each fastened to the corresponding fastener of the angular sector, at least one of the balancing masses also acting as a fastener for fastening the angular sector on the bearing face.

A self-adhesive balancing weight for a vehicle wheel has a top surface and a bottom surface with a self-adhesive tape. The bottom surface has a first curved section with a first radius and a second curved section with a second radius. The first radius is smaller than the second radius. This allows to hold the balancing weight by the adhesive tape to almost every rim, as there are always at least two holding points (-lines) by which the balancing weight contacts the rim via the adhesive tape.
